Abstract

The invention provides a heterogeneous network per-bit energy minimization resource distribution method based on rate limitation. The method includes the following steps that firstly, an intelligent centralized controller collects available bandwidth resources in a heterogeneous network, wherein the bandwidth resources are total flow bandwidth of radio frequency resources in the heterogeneous network; secondly, the intelligent centralized controller collects resource use applications of user equipment; thirdly, the intelligent centralized controller distributes frequency resources in the heterogeneous network according to an artificial bee colony algorithm. The resource distribution method is efficient and reliable, the energy utilization efficiency in the heterogeneous network can be remarkably improved, and energy consumption of the heterogeneous network is reduced.

Description

Technical field [0001] The invention belongs to the technical field of computer networks, and particularly relates to a method for minimizing energy per bit of a heterogeneous network based on rate limiting. Background technique [0002] The purpose of green wireless communication is to adopt energy-saving operations in wireless communication systems to address the increasing energy consumption in cellular networks. Today, the number of global mobile phone users is close to 6 billion, of which wireless devices and equipment consume approximately 9% of the total information technology energy (that is, up to 610 million kilowatt hours). Recent surveys show that the operation of cellular networks requires approximately 80% of the total energy, including the energy consumed by base stations, user equipment and core networks. In addition, the number of mobile user equipment and the demand for capacity per user continue to grow. Therefore, research on next-generation mobile network d...
